Weblength, subject age, height, and femur contour points. The second method, SSM+TPS, utilizes a previously developed statistical shape model (SSM) and thin plate spline (TPS) morphing to better conform an approximated SSM-derived shape to that of the radiograph. For each femur in the test set, the original CT- WebAug 12, 2024 · Tps R Documentation Thin plate spline regression Description Fits a thin plate spline surface to irregularly spaced data. The smoothing parameter is chosen by generalized cross-validation. The assumed model is additive Y = f (X) +e where f (X) is a d dimensional surface.

Webv.surf.tps performs multivariate thin plate spline interpolation with regularization. The input is a 2D or 3D vector points map. Values to interpolate can be the z values of 3D points or the values in a user-specified attribute column in a 2D or 3D vector map. Output is a raster map. Optionally, several raster maps can be specified to be used ... Thin plate splines (TPS) are a spline-based technique for data interpolation and smoothing. They were introduced to geometric design by Duchon. They are an important special case of a polyharmonic spline. Robust Point Matching (RPM) is a common extension and shortly known as the TPS-RPM algorithm. See more The name thin plate spline refers to a physical analogy involving the bending of a thin sheet of metal. Just as the metal has rigidity, the TPS fit resists bending also, implying a penalty involving the smoothness of the … See more TPS has been widely used as the non-rigid transformation model in image alignment and shape matching. An additional application is the analysis and comparisons of archaeological findings in 3D and was implemented for triangular meshes in … See more The thin plate spline has a natural representation in terms of radial basis functions. Given a set of control points $${\displaystyle \{c_{i},i=1,2,\ldots ,K\}}$$, a radial basis function defines a spatial mapping which maps any location $${\displaystyle x}$$ in … See more • Elastic map (a discrete version of the thin plate approximation for manifold learning) • Inverse distance weighting See more • Explanation for a simplified variation problem • TPS at MathWorld • TPS in C++ • TPS in templated C++ • TPS interactive morphing demo See more

WebJul 19, 2024 · Put it within this buffered area (imbuffer) which is also 0s. Then the result is this black image. So the array contains only 0s. I resampled the initial image in order to avoid the small black area at the corner, hence not to contain 0s. Following i added the buffer area, so I have a zero area around the image. cpf cristianeWebMar 19, 2015 · Thin plate spline works perfectly for all GCP you have entered, but possibly not for the rest of the image. If you use polynomial interpolation, you get residuals for all GCP points. If one or several of your GCP have a low accuracy, the polynomial interpolation can compensate that, leaving the image as a whole with less distortion. disney world tickets discounts couponsWebIn §5we discuss the (dis)advantages of using smoothing splines for in-terpolation. 2 1-D spline interpolation To illustrate how splines work, we begin with interpolation in one di-mension by smoothing splines [9, §5.4] [18, §8.7].
